Patented Feb. 7, 1933 UNITED STATES PATENT .OFFICE MICHAEL MAUL, 0F BERLIN, GERMANY, ASSIGNOR TO THE TABULATING MACHINE COMPANY, 0F ENDICOTT, NEW YORK, A CORPORATION 0F NEW JERSEY ACCOUNTING MACHINE FOR PUNCHING TOTALS Application Med July 80, 1927, Serial No. 209,457, and in Germany November 20, 1926.

This invention relates to accounting systems wherein data on record `cards or sheets bearing index points is automatically read, computed, printed, etc. In such systems, it is often found desirable to utilize cards wherein data punched thereon includes items entered into an accumulator of'an accounting device.

The object of the present invention is to trol the selection of printing elements andpunching elements by the same accumulator to respectively print and punch the data entered into the accumulator.

Referring to Fig. 1. B indicates the card punching structure. The latter is described in detail in the U..S. Patent No. 1,821,078 owned hy the assignee of the present invention. In brief, the operation of the punching mechanism is as follows: A stack of cards to be punched is placed in magazine 10. The operator draws outa rod 11 which carries one end of the machine, re-operates pull-rod 11 and punches the next card. For each index position on the card, a unch 1.2 is provided, a series of said punches eing placed in a row across the device. Corresponding to each punch is a finger key 13 for manual operation. Action of the key serves to depress plunger 14, which by rocking bell crank 15 pivoted thereto at 16, thrusts forward an interposer bar 17 to an advanced position over its corresponding punch 12. The forward movement of an interposer rocks an arm 18 in its path, which pulls a link 19 forward and thus closes contacts 20. This establishes a circuit to themain punching magnet 21 which attracts its armature 22. An arm 24 (Fig. 3)mis fixed to a rock shaft 60 to which is also aliixed a bail 23. The free end of arm 24 is connected to armature 22 by an adjustable link 61 so that attraction of the armature causes shaft 60 to rock, thereby lowering bail 23 from a normally raised position shown in Fig. 2 to the lower position shown in Fig. 3. Bail 23 is directly over the row of punches 12 and when rocked downwardly depresses any of the interposer bars which have been moved forward, and thereb orces the punch or punches through the card. Punches Whose interposcr bars have not been thrust forward will not be affected, as they will be in the position shown in Fig. 1 with the clearance notch 25 under the bail. Contact 26 (Fig. 1) is provided to cut outthe punch selecting magnets 42 while pull-rod 11 is being operated in order to prevent punching operations during that time (as fully explained in aforementioned yPatent No. 1,821,078, page 13,1ine 111 through escapement mechanism operates to feed the next card column under the punches 12. The card being punched rests on top `plate 62. A card carriage comprising a rack 63 has an extending arm 64 at the rear carrying a pivoted member 65 which drops behind the rear edge of the card being fed and ahold-down cam gripper 650 which engages and holds down the forward end of this card. The rack 63 has gear teeth on its lower edge meshing with a gear 66 forming part of the casing of a drumenclosing a spiral spring. As the carriage is moved to the right in Fig. 3 the rack rotates gear 66 and tensions the drum spring which thereupon tends to move the carriage back to thel left.` This movement to the left is controlled by escapement mechanism responsive to the punching operation. A bail 70 is mounted on shaft 71 and extends beneath all the interposer bars 17 so that when an interposer is lowered to eHect punching the bail 70 is rocked counterclockwise against the action of abiasing spring (not shown). A pawl 73 is loosely mounted on shaft 71 and a spring 72 attached to an extending arm of the pawl tends to force it into engagement with a series of notches formed on the upper edge of rack 63. A second pawl 80, pivoted on the machine frame, cooperates with pawl 73 to form an escapement. A double arm member 81 is also mounted on shaft 71 and arranged to be operated by bail 70. This member is connected to pawl 8O through a pin and slot connection and to pawl 73 by means of a pin 75 engaging an enlarged hole in the pawl. Normally when the bail 70 is in raised position the member 81 holds pawl 80 free of the ratchet teeth and holds pawl 73 in engagement with one of them.

On a punching operation the lowering of one of the interposers 17 moves bail 70 downward and consequently rocks member 81. This first moves pawl 80 intoengagement with the ratchet teeth to hold the card carriage against movement temporarily and then, owlng to the cooperation of pin 75 with 'the enlarged hole, raises the pawl 73 free of the ratchet teeth. The spring 72, on account of the loose mounting of pawl 73 moves it slightly into position to engage the next ratchet tooth. Then, on the rise of bail 7 0 after the punching in the particular card column, the pawl is raised and the card carria e moves until pawl 73'engages the next ratc et tooth stopping the carriage with the next card column under the punches. This mechanism is well understood and fully described in the Patent No. 1,821,078 heretofore mentioned and in patent to Schaai, No. 1,426,223, August 15, 1922.

The manual operation of the punching mechanism above described is, by means of this invention, to be combined with an automatic operation of the punches controlled by counting or computing mechanism, prefer- 639,153, filed May 15, 1923, owned by the assignee of the instant case now Patent No. 1,822,594. The accumulator driving, carrying, and other mechanism related to the accumulators are all well known features of the prior art (see for example Lake Patent No. 1,307,740 for driving features of the accumulators and refer therein to page 2, lines 119 and 122 and see Hollerith Patent No. 974,272 for the transfer mechanism).

In Fig. 4 (corresponding to Fig. 20 of Patent No. 1,822,594) is shown one of the tabulating counter sections of the Lake tabulator. Each counter section includes counterv magnets 27 vfor controlling the movement of counters 28 in accordance with the index points on the'record -card then under the lower one of two sets 0f analyzing brushes. The tabulating machine, as explained in detail in Patent No. 1,822,594 has an automatic control which changes the operation of the machine in accordance with the groups `of cards having been tabulated. This control is exercised from a selected group of index points in adjacent card columns. So long as each consecutively fed card has the same group of index points as the preceding card the machine will continue to accumulate the items on the cards and may also list them. When the selected group of index points of a card is not the same as that of the preceding card, the

automatic control operates in either of two ways, depending on. the preliminary settingof certain control switches. According to one mode of operation, the automatic control vstepped cam 31 which is geared to the counter whee-l and thus always positioned according to the reading on the Wheel. The position of this cam is felt out during totaling by a rockable linger 32. When an adjustable screw 33 on the end of this finger encounters the uppermost step of the'cam 31 contacts 34 and 35 are closed to energize printing magnets (not shown) to selectthe type for printing which correspond to the reading of the counter wheel. The purpose of the present invention is to automatically punch on a record card, the readings, of a certain group of said counters after they have come'to rest.

The readings punched will obviously be the totals of the items in certain columns of the last group of tabulated cards. This punching may be either in addition to or in lieu of total printing. Geared to each counter wheel 28 (Fig. 4) through an idler .ear is a gear wheel 36 freely rotatable on s aft 37. Associated with each gear 36 is a stationary contact ring 38, fixed to a stationary shaft 3 and insulated therefrom. Encircling each ring 38 and fixed thereto is a commutator ring 39. The commutator ring is provided with ten conducting segments 40 insulated from each other and from the contact ring 38. A brush 41, fixed t0 gear 36 to rotate therewith, is in constant engagement with ring 38 and is adapted to contact segments 40 successively to conductively connect the segments in turn with the ring 38. Each of the segments 40 corresponds to a numeral on the counting wheel 28 and when a particular numeral ou the wheel is at reading position, the segment 40 corresponding to said numeral willY be in Contact with the brush 41.

Each gear 36, contact ring 38, commutator ring 39 and brush 41 constitute a punch selecting unit. There are as many such selecting units as the number of counting Wheels but for the purposes of illustration, only three are shown in Fig. 6, the one characterized by an a after its reference numerals being controlled from the units counter 28a of a group of adjacent denominational order column counters, the selector unit with b after the reference characters corresponding to the tens counting Wheel of said group, and the one with c corresponding to the hundreds counter of the group.

In series with each of the commutator segments 40 is a magnet 42 corresponding to and adapted for actuating one o the interposers 17. The magnets are connected at one end by a common lead 43 to similar segments on each of the commutator units. Since only one column at a time is punched, only ten selecting magnets are provided for cooperation with all of the tabulating counters. Each magnet corresponds to the numeral characterizin the commutator segments with which 1t is in series and operates the punch for perforating the card to designate said numeral.

The aforementioned punch selecting units and the magnets 42 are associated with a column selector commutator in the punching machine. T his commutator comprises a frame bar 47 fixed to the punch frame 470 in anv suitable manner, as for example, by an end bracket 471 and a bottom angle bracket 472 (see particularly Fig. 8). Mounted on top of frame bar 47 and insulated therefrom is a rear contact rail 45 and insulated from the latter is a row of contact sections 46 insulated from each other and carried by the bar 47.

The magnets 42 are in series with one side of a source of current 44, the other side of which connects to the contact rail 45. The center lines of sections 46 are a card column apart and the number of sections equals the number of columns on a card. Rigidly connected with the card holding carriage of the punching mechanism by means of a bracket 473 i secured to rack 63 and a plate 474 is a contact piece 48 (Figs. 1, 7 and 8) for conductively connecting contact rail 45 and the sections 46. As the carriage, after a punching operation, moves a distance of one card column, the contact piece 48 also moves the same distance and thus connects each of the sections 46 in succession to the rail 45.

Each of the contact rings 38 of the selectors, except the one corresponding to the units counter, is removably plugged to one of the contact sections 46. For apurpose hereinafter set forth, the units counter ring 38 is connected to rail 45 through normally open contacts 50, the lead 51a from the ring belng removably connected to one side of contacts 50. The ring 381) of the commutator for the tens counter 1s removably connected by lead 51b to the section 461) corresponding to the card column in which the data on said tens counter is to ybe punched. The ring 38e is removably connected by lead 510 to the section 46c corresponding to the card column in which the data on the hundreds counter is to be punched. Thus if the data on the units counter is to be punched in the twentieth column of the card in the punching mechanism, the tens counter 286 will be associated through the rin 38b with section 46b corresponding to t e twenty-first column and the hundreds counter will be associated through ring 38e with section 46c corresponding to the twenty-second card column. The removable connections of the rings 38 to column sections 46 permits selective association of any of the counting wheels with any of the column sections. t

The mode of operation of the parts described is as follows: The operator manually `actuates keys 13 to perforate data in the card columns preceding those which are to be perforated automatically in accordance with the reading on the counters of said tabulating machine. Inthis preliminary manual operation of thepunchin'g machine, if any 'column is not to contain any of items lto 9, the 0 key may be depressed to cause the 0 osition of the column to be perforated. I it is not desired to thus perforate columns in their zero position, the operator depresses the skip key (see Fig. 1 as is well understood in the art. This s ip key shown in Fig. 1 advances an interposer 17 and causes its depression to effect a feeding operation in the same way as any numeral key. The particular interposer connected to the skip ey 1s not, however, provided with a`forward portion such as 25 to engage any punch. Therefore, upon its depression, there is no punching operation but only a feeding operation as above explained. The details of this particular skip key construction are fully disclosed in Patent No. 1,803,979. Due to the geared connections of the commutator brushes 41 to the counters the commutator brushes will rotate in synchronism with the counters and when the counters are at rest, will contact with the commutator segments 40 corresponding to the reading on the counters. The punch carriage 49 in the meanwhile, has been moved so that the bridging contact 48 overlies section 46a corresponding to the units column of the item to be punched. The punching of the card in this column in accordance with the reading of the units counter is placed under control of the punch operator in order thatupon the completion of a manual punching, the automatic punching may not follow directly without the knowledge of the operator. For this reason, the units sliding ring 38a is not connected to section 46a but to the common contact rail 45 through the normally open contacts 50 as hitherto explained. The card column corresponding to the units counter being under the row of punches after the tabulating machine is at rest, the operator depresses key 52 closing contacts 50, completing the circuit through one of the magnets 42 which thereupon attracts its armature 53 (Figs. 1 and 3) depressing plunger 14 and effecting an operation of the punch as in the manual operation. The punch carriage 49 after the punching operation automatically advances the card to the next column moving bridging contact 48 with it to connect contact section 4Gb with the common bar 45; A circuit is thereby completed which energizes the magnet 42 in series with the commutator segment 406 engaged by the commutator brush 41?). Magnet 42 upon energization eiects thepunching of the card in said column. As the carriage continues to move a column space after each punching operation, the contact sections 46 are successively engaged by the contact 48 to automatically cause punching of the reading on the counters associated with the successive sections 46.

It is understood that the particular punching device herein described is not necessary to carrying out the invention, but similarly functioning punching devices may also be used in connection with the invention. It is also obvious that the accumulating means to be used are not necessarily those described herein but that it is Within the scope of this invention to associate any similar accumulating mechanism with selectors for automatically operating a punching device to punch the data standing on the accumulating mechanism.
